I had been told by the other English teachers that I work with that they often get children who call them Meegugin (미국인) or Weegugin (외국인) (also pronounced meegukin or weegukin, depending on your pronunciation). A meeguk is a person from America, and a weeguk is a foreigner. Conversely, a hangukin (한국인) is a Korean person. Apparently this isn't just like children pointing out that someone has on a funny hat or looks different. It's actually rude to call someone either of these names, though we often call ourselves 미국 to differentiate us from Canadians, etc. The main reason it's rude, is that the children think we don't know what they're saying. It's akin to calling someone a name in a foreign language right in front of them, just because you think they won't understand you. I hadn't actually encountered this until today.
I was in the elevator on my way back up to work, and there were two children in the car with me. Just before it got to my floor, I heard the word weegugin come from the one closest to me. I turned to look at him, and they were both looking at me and giggling. So as I got off the elevator, I patted the one who spoke on the head, and said "Hangukin", and then walked out. I didn't see their faces, but they both stopped giggling.
(and yes, I can read a little bit of Korean now! 아싸 !)
